As a foreigner living in the UK, I concur. All .gov.uk are _extremely_ functional. Applying for the pre-settled status (cos Brexit) was actually an enjoyable experience! I had no idea what was going to happen when I started the process, and it was all done in 30min top. It made me _scan my passport with my smartphone_ while flashing weird colors and it worked flowlessly, that absolutely blew my mind.
I've actually looked into getting a job there even though I'm from a start-up background
